The St. Regis Mexico City

The St. Regis Mexico City is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The St. Regis Mexico City rather than just read about it. In short: Freedom Tower (also called the St. Regis Hotel Tower) is a skyscraper located in front of the Diana Fountain roundabout at Paseo de la Reforma 439, Colonia, Cuauhtémoc, Delegación Cuauhtémoc in Mexico City.

Key takeaways

The St. Regis Mexico City belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect The St. Regis Mexico City to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The St. Regis Mexico City from memory before moving on to harder problems.

Reference excerpt

Freedom Tower (also called the St. Regis Hotel Tower) is a skyscraper located in front of the Diana Fountain roundabout at Paseo de la Reforma 439, Colonia, Cuauhtémoc, Delegación Cuauhtémoc in Mexico City. Its construction began in November 2004 and completed in January 2008. The tower started operating in June of that same year. The building has a commercial area on the first to third floor, and a seven-level underground parking garage with a capacity for 2,000 cars. As of 2010, the Freedom Tower was the second tallest building in Paseo de la Reforma and the ninth tallest in Mexico City. The tower consists of a hotel and various luxury residences. This is the first building belonging to the St. Regis Hotel & Residences in Latin America. The architect of this skyscraper was the Argentinian Cesar Pelli, creator of the Petronas Towers in Kuala Lumpur - the highest building in the world until the year 2004. In Mexico City he previously designed the Twin Towers of Polanco called the Forest Residence 1, the Forest Residence 2, and the Coca-Cola Building in 1995.

Form The building reaches to 150.1 meters at its spiral. The height to the top floor is 138.3 meters, and up to the roof it reaches 144.5 meters. The building has 32 floors; the floor to ceiling height of each floor is four meters. The building is equipped with 15 high speed elevators that move at a speed of 6.6 meters per second. In addition it has three pressurized emergency escalators, automatic units for air conditioning, and mechanical and electrical and facilities on each floor. Each floor has an average area of 1,750 to 1,825 square meters, free of columns. The total area of the building is 78.900 square meters. The site was formerly used as a public parking lot. It is sometimes referred to as the vase building due to its construction and external appearance.

Important Details The initial project (and official name) is Freedom Tower, but it is now commonly known as the St. Regis Tower. Because of the high seismic activity observed in Mexico city, prior to its construction, a highly advanced seismic engineering study was conducted. This allowed the designers to isolate it properly and protect the building from the common earthquakes that happen in the city. To do this, the structure is anchored to the surface of the earth and supported by 225 concrete piles, which penetrate to a depth of 55 meters passing the marshy land into firmer ground. The building is also equipped with 65 seismic shock absorbers. With this, it can withstand an earthquake up to 8.5 degrees on the Richter scale. On April 13, 2007, it withstood an earthquake of 6.3 on the Richter scale. Also, in June 2009 another one of 6.4 intensity on the Richter scale. The tower can also resist winds up to 257 kilometers per hour. The glass panes used to build it have a thickness of 2.3 centimeters.

Worked examples

Example 1 — a first encounter with The St. Regis Mexico City

Start with the simplest possible case. Write down what The St. Regis Mexico City claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The St. Regis Mexico City before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The St. Regis Mexico City ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The St. Regis Mexico City

In research: The St. Regis Mexico City appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses The St. Regis Mexico City in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: The St. Regis Mexico City is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 2009, César Pelli buildings, Hotel buildings completed in 2009, so understanding it makes those chapters shorter.
In everyday life: Look for The St. Regis Mexico City outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
